Photo of the Day: London Olympics Traffic

An ambulance drives along an Olympic Lane on the A4 road into central London Wednesday, July 25, 2012, as a sign indicates that only official Olympic traffic may use the lanes. Confusion, frustration and delays reigned on London's congested roads Wednesday, as lanes reserved for Olympic VIPs came into force two days before the start of the games. The 30 miles (48 kilometers) of lanes are to operate from 6 a.m. to midnight throughout the games, and cars or taxi cabs that stray into them face a 130-pound ($200) fine.
